Woo Ji-ho studied music and art in Japan as a teenager and came back to lead Block B, the seven-member group that debuted in 2011. His solo career began in November 2014 with "Tough Cookie", a single with Don Mills. A year later he was a producer on Show Me the Money 4, and "Boys and Girls" and the EP Gallery followed.
In 2018 he left Seven Seasons, Block B's agency, and early in 2019 he started his own label, KOZ Entertainment. His first studio album, Thinking, came out in two parts that year and dealt openly with loneliness. Then came "Any Song". Before it was even out, he posted clips of himself dancing to it with Hwasa and Chungha. Fans and stars copied the simple moves by the thousands, and the song ruled Korean charts for the first half of 2020.
Zico works on both sides of the studio glass. He co-produced "Bermuda Triangle" with Crush and Dean, wrote for other artists and, after his military service, became executive producer of BOYNEXTDOOR at his own label, which joined the HYBE family. His own releases pull in big names: "Spot!" with Jennie in 2024, "DUET" with YOASOBI's Ikura, singing as Lilas, in late 2025.
His latest single is still "DUET", released a week before Christmas 2025. In January 2026 he returned to Show Me the Money for its 12th season, again as a producer and this time paired with Crush. No new album has been announced. He has said, though, that he wants to make something on the scale of an album again, since Thinking is still his only full-length record.
